6 Claims. Cl. 248-58) This invention generally relates to a supporting device for cables, and more specifically provides a clamp-on type of cable hanger especially adapted for use inmines wherein it is desirable to support various cables in suspended relation from the roof bolts normally employed in mine construction.

An object of the present invention is to provide a cable I 54 will move the end V I outwardly. The support member 38 is pivoted to the portion of the jaw member 12 immediately above the These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being bad to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a side elevational view of the cable hanger of the present invention attached to a roof bolt in supporting position for holding a plurality of cables;

Figure 2 is a plan sectional view taken substantially upon-a plane passing along 1 illustrating the association bolt head;

Figure 3 is a plan sectional view taken substantially upon a plane passing along section line 33 of Figure of the gripping jaws and the section line 2-2 of Figure 1 illustrating the specific construction of the jaw actuating mechanism;

Figure 4 is an enlarged view showing the construction of one of the V-shaped gripping jaws;

Figure 5 is a 1 illustrating a modified form present invention; I

Figure 6 is a side elevational view similar to Figures -1 and 5 illustrating another modified form of 'cable ing bolts; and Figure 7 is an end elevational view of the construction of Figure 6 showing further details thereof.

Referring now to the drawings, it will be seen that the numeral 10 generally designates the cable hanger of the present invention as illustrated in Figures 1-4. The cable hanger includes a first jaw member 12 and a second jaw member 14, each of which is arcuated, and a horizontal portion 16 of the second jaw member 14 is pivotally secured to the first jaw member 12 by a pivot pin 18. The upper ends of the jaw members 12 and 14 terminate in inwardly facing V-shaped gripping jaws 20 and 22, respectively. Each of the'jaws 20 and 22 is provided with a V-shaped facing surface 24 having a plurality of horizontal serrations or grooves 26 therein side elevational view similar to Figure f ofthe cable hanger of the for securely gripping the head 28 of a roof bolt 30 member 38 having an upturned outer end. .inner end pivotally connected to'a engage between a washer'68 and surface 70 wherein the washer 68 is secured thereto by 2 ,923,508 Pat F 2 ,1960

mounted in the roof 32' of a mine or in any other "desired position. Also, a suitable washer 34 is provided between the head 28 and bolt. The V-shaped surfaces 24 of the jaws20 and 22 on the jaw members 12 and 14 securely grip the bolt head 28 for supporting the same in suspended relation thereon. g

The-lower end of the first jaw r'nember;12 depends below the pivotal connecting pin 18 and terminates in a laterally extending portion 36. Pivotally securedto the first jaw member 12 between the pivot pin 18 and the laterallyextending portion 36 is an elongated support 40 and an designated by the numeral 42 and portion 44 pivotally secured to the by a pivot pin 46 and a second end member 48 pivotally secured to a projecting lug 50 on the second jaw '14:by a pivot pin 52. A double and oppositely threaded member 54 interconnects the ends 44 and48 of the'turnbuckle 42 wherein adjustment of the threaded member members 44 and 48 inwardlyand including a' first end support member 40 lateral extension 36 by a pivot pin 56 wherein downward movement of the free end of the support member 38 will cause'movement of the second jaw 14 towards the first jaw member 12, thereby causing the jaws 20 and 22 to be urged together for secure clamping engagement with the bolt head 28 whereby a plurality of cables 58 mounted on the support member 38 will be supported. It will-be noted that the laterally extending portion 36 of the jaw member 12 is constructed of spaced members for receiving the support members 38 therebetween. The weight of the cable58 acts to'increase the clamping engagement of the jaws 20 and 22 with the bolt head 28 wherein the more weight added onto the support 38 will increase the clamping action of the cable hanger. 10.

Referring now specifically to the modified form of the invention illustrated in Figure 5, it will be seen that the numeral 60 generally designates a modified form of the invention including a pair of generally vertically disposed jaw members 62 and 64 which are provided with inturned pointed upper ends 66 which are adapted to the roof or supporting a suitable fastening bolt 72. At'the lower end of the first jaw member 62, an elongated member 74 is provided which extends to both sides of the jaw member 62. Adjacent the outer end of the elongated member 74 is pivotally attached the second jaw 64 by a. pivot pin 76. Pivotally secured to the jaw 62 above the member 74 is an elongated support member 78 having an hanger'where the hanger is dependent from the tsupportupturned free end 80 and an angulated portion 82 adjacent the other end'thereof and on the opposite "side of the pivotal connection 84 to the jaw member 62. The end of the angulated portion 82 is pivotally connected to one end 84 of a turnbuckle generally designated by the numeral 86 and the other end of the turnbuckle 86 is designated by the numeral 88 and pivotally connected to the lower end of the jaw 54 by pivot pin 90 in spaced relation to the pivot pin 76. A central threaded member 92 is provided on the turnbuckle 86 together ing a suitable wrench for rotation thereof whereby the effective length of the support member 78' may be adjusted; thereby adjusting the clamping characteristics of the pointed ends 66 on the jaw members 62 and 64 face of the support members 78.

The cable hanger 96 generally in cludes a first arcuate jaw member 98 and a second arcuate jaw'meinber 100 whereinthesecond arcuate aw member ris provided with a horizontal portion tached tothe jaw mernber 98 by pivot pin 104. The with jaws lilfi and 108 that receive-'andengage the headed portion 110 of the bolt 112 for clamping the cable hanger 98 thereto. Extending from the first jaw 98 in generally depending relation is an elongated offset member 114. Pivotally secured by pivot pin 116 adjaupper ends of the jaw members 98 and 100 are provided .cent'tliel center of the member 114 is an elongated sup-,

port arm 120.1 The elongated support arm 120 is provided with a flexible support member 122 at the lower .end thereof and the lower. end of the member'114is also provided withla flexible support member rl24 'for supporting a suitable load; Extending of the support member 120 and the juncture between the arcuate-jaw member and the-horizontal portion 102 thereof is a turnbuckle generally designated by the nurneral 126 which includes a first end portion 128 and a second end portion 130 that are movably interconnected i by a double and oppositely threaded portion 132 which forms a turnbuckle whereby the adjustment of the turnbuckle 126 will permit the clamping characteristics of the jaw members 98 andltltl to be adjusted as desired or as may-be necessary for supporting a desired load;

The foregoing is considered vas illustrativeonly oflthe principles of the invention. Further; since numerous modifications and changes will'readily occur to those skilled in the'art, it is not desired to limit the invention to end portions into clamping engagement with an overhead 2.
